Just thought I would say how much mental attitudes affect heart rate ... I track my heart rate carefully, won't bore you with the sordid detail! ... on Sunday I did W2R3, heart rate got to about 114. Today did W3R1, heart rate got to 131. Yesterday went to the dentist to get a broken tooth fixed, heart rate got to 147. I hope it's taught me to relax and trust Laura, I'll hope so. Trust Laura, gradually getting there!
